Its a CFNM fetish group. Here is how this probably works. Dudes wanting to get their jollies, pay "studio owner" lets say $150 per hour. "Studio Owner" in turn recruits not so sharp women ( or willfully kinky women ) to "take pictures" of said males. The males get their fetish fix by being viewed nude by a clothed woman and the "photog" and "studio owner" get some money. The sad part is, its probably 100% serious.
